Title: Constant current circuit
Inventor: SHINOHARA SADAO
IPC: G05F3/30
Filed: 1986-02-26
Abstract: PURPOSE:To obtain an optional current with variation of the gate voltage and at the same time to attain a constant current circuit that is advantageously converted into an IC, by preparing a band gap constant voltage circuit and dividing the constant voltage level into several steps to set a drain current in the form of the gate voltage of an optional MOS transistor. CONSTITUTION:A band gap constant voltage circuit 1 obtains plural constant voltage levels by providing plural resistances to a band gap circuit and contains bipolar transistors Q1-Q4 are resistances R1-Rn. While MOS transistors T1-Tn use the constant voltages VG1-VGn obtained from the circuit 1 as the gate input. A constant current flows through the circuit 1 and constant voltages are obtained at points (a) and (b). Therefore the constant drain currents ID1 and IDn are obtained through the transistors T1 and Tn respectively.

IPC: H04N1/40
Filed: 1986-02-26
Abstract: PURPOSE:To discriminate accurately the image tone of a read image by providing a means for inverting adjacent binary-coded data to a noted picture element and giving a discriminating data means when the binary-coded threshold value is a 2-dimensional smoothing value of a density data and the density data is nearly equal to the smoothing value. CONSTITUTION:When the binary-coded threshold value is a 2-dimensional smoothing value of density data and the density data is nearly equal to the mean value, the binary-coded data adjacent to the noted picture element is inverted. That is, a frequency counter circuit 3 counts the number of inverted binary-coding signal from a binary-coded circuit 2 at each prescribed region of the read image, outputs a select signal to a switch 6 based on the result of counting, the switch 6 selects either a binary-coding signal from the circuit 2 (via a delay circuit 8) or a binary-coded signal from a dither binary-coding circuit 5 (via a delay circuit 9) at each noted picture element and supplies the result to a printer. The delay circuits 8, 9 match the timing between the output signal from both the circuits 2, 5 and the select signal from the circuit 3.

Title: Grain detection apparatus
Inventor: TOKI HARUMITSU
IPC: G01N21/3554
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To accurately judge three or more kinds of grains by utilizing the quantity of the surface moisture of grains by irradiating grains with electromagnetic waves having a moisture-absorbed wavelength and comparing the detected voltage value of the quantity of detected reflected light with a judge standard value to discriminate grains. SOLUTION: Grains are irradiated with the moisture-absorbed wavelength light in the electromagnetic waves from the light emitting part 1a of a grain sensor 1 and the quantity of the reflected (permeated) light is detected by a light detection part 1b to be transduced to a voltage value which is, in turn, inputted to a CPU control part 2. The control part 2 presets a discrimination voltage region of three kinds of unpolished rice, bad rice and unhulled rice corresponding to the kind of grains on the basis of the detected voltage value to judge at least three kinds of grains. That is, the small, medium and large regions of the detected voltage value are set to an unpolished reference region, a bad rice reference region and an unhulled reference region on the basis of a frequency distribution graph.  The detected voltage value of the senior 1 is compared with the respective reference regions to be discriminated and, when detection data reaches a predetermined number of grain kinds, an unpolished rice ratio, a bad rice ratio and an unhulled rice ratio are calculated.

Title: Iron making method by melt reduction
Inventor: FUJII TAKASHI
IPC: C21C5/34
Filed: 1985-02-28
Abstract: PURPOSE:To eliminate the need for the desulfurization on the outside of a refining furnace and to avert the loss of time for the desulfurization by blowing or adding iron ore, coal, lime and gaseous O2 into the molten iron in the furnace and blowing a desulfurizing flux into the molten iron through the tuyeres in the lower part of the furnace upon ending of reduction refining. CONSTITUTION:The prescribed amt. of the molten iron 10 as a seed hot metal is charged into the refining furnace 1 and thereafter O2 is blown at a prescribed flow rate through the tuyeres into the molten metal 10 in the furnace 1. The iron ore ground to a prescribed grain size or below is blown with a process gas as a carrier gas through the tuyeres 3 into the molten iron 10. Respectively prescribed amts. of granular quicklime and coal are blown at the same instant through the tuyeres 3 into the molten iron 10. On the other hand, the gaseous O2 is ejected at a prescribed rate from a lance 8 toward the molten iron 10. The blowing of the gaseous O2 and iron ore, etc., is stopped after the refining of the iron ore in the furnace I and the desulfurizing flux is blown together with a carrier gas such as gaseous N2 through the tuyeres 3 into the molten iron 10. The concn. of the sulfur in the molten iron tapped 6 from the furnace is thereby decreased to about 0.03%.

Title: Remote control transmitter
Inventor: OGITA MINORU
IPC: H04B10/11
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To keep operability high even in the case of providing a lot of button switches on a simplified and miniaturized remote control transmitter. SOLUTION: Button switch groups 4 and 5 are respectively provided on both a front face 2 and a rear face 3 of a remote control transmitter 1. Thus, since the button switch groups are provided on both the sides of a main body, the number of button switches can be increased while keeping the main body compact. Further, a gravity sensor 6 is provided inside, the vertical position relation of the remote control transmitter 1 is detected, only the button switches on the upper face are validized, and the ON/OFF of button switches on the lower face is ignored.  Thus, even when the transmitter is operated while holding it with a hand as conventional, since the ON/OFF of button switches on the lower face covered with the hand is ignored, the transmitter can be held with the hand without considering this ON/OFF and even when the transmitter is put on a table or the like and abutted to any projecting object and the button switches on the lower face are turned on, no erroneous code is transmitted.
